Ubuntu Mate is meant to be used graphically. That is to say you need a monitor and keyboard to use it.
Quote from the ubuntu mate website.

NOTE! There are no predefined user accounts. The first time you boot one of the desktop images it will run through a setup wizard where you can create your own user account and configure your regional settings.

No user account by default means you cannot login remotely. There is no user to log in as.

I was wondering will my Pi be damaged if I never shut it down/if I just keep it running indefinitely?

Hi. I have RPi 1 model B and B+ hardware running about 29 months and I have RPi 2 hardware that has been running 13 months. Out of a total of 10 RPIs operating pretty much continuously for a year or more, I have had no failures, but one scare which turned out to be the power supply, not the RPi. None of them use any aftermarket heatsinks or fans. Half of my Pis are in the little plastic cases https://www.adafruit.com/products/1997 you can buy, half are in larger plastic enclosures. All are operating indoors at normal room temperature for humans, no unusual or special environmental conditions.

I just got my raspberry pi, I tried to run the 'startx' and showed up the message 'FATAL: Module g2d_23 not found.'. Even though I have read that this can be ignored, nothing happens.... I don't get a nice screen with a raspberry like I've seen in other places. Can someone take me through this, please? (really frying my newbie brain here )

Hey folks. I recently installed Debian Stretch onto a 32 GB card and it loads up fine, but, i never got the initial setup screen, thus did not get to set up my Root password. Still new to Linux, and no clue how to proceed from here.

I really don't know what's this Raspberry Pi? Is it a mother board for PC?

From the FAQs:1. WHAT IS A RASPBERRY PI?

The Raspberry Pi is a credit-card-sized computer that plugs into your TV and a keyboard. It is a capable little computer which can be used in electronics projects, and for many of the things that your desktop PC does, like spreadsheets, word processing, browsing the internet, and playing games. It also plays high-definition video. We want to see it being used by adults and children all over the world to learn programming and digital making.

Basically it is a small computer. Not as fast as a modern PC, but what do you expect for that price? You can't use Windows programs on it, but you can choose from over 15,000 "packages" of programs for it with many of the things you'd normally run on a PC, plus a load more as well. Read through some of the posts on this forum to see some of the amazing projects people have used their Raspberry Pi for. I have used them to control my heating, some lights, run a webserver, drive printers, be a smart doorbell, video wildlife, manage my shopping, catalogue an entire library (around 13,000 books), control lights on my christmas tree and a load more.
